Description
Technical field:
The utility model relates to a kind of optical theodolite that utilizes laser aiming and centering method increase lighting circuit through having improved, particularly a kind of laser alignment formula optics longitude and latitude determinator.
Background technology:
In today of information and high-tech fast development, robotization and intellectuality constantly become the science and technology development main flow.Under the influence of social development megatrend, instrument of surveying and mapping manufacturer stagnates with development gradually to the exploitation of conventional optical instrument.But, with regard to the ordinary optical transit, because its low price, simple to operate, still be subjected to the welcome of medium and small civil engineering enterprise at present.Though advanced electronic device automaticity such as total powerstation height, multiple functional owing to it costs an arm and a leg, the more high shortcoming of cost, has limited its teaching test in conventional use of medium and small enterprise and common big or middle universities and colleges and has used.
The ordinary optical transit has many restriction defectives in daily use, as in civil engineering, in the tunnel with carry out engineering survey work at down-hole, night and need 2～3 people to cooperate to finish, the one man operation instrument, one people holds up scale to hold concurrently and is responsible for the scale illumination, an other people is responsible for theodolite reading circle illumination and data recording, has restricted project progress; Aspect big, the gyp of intermediate court journey MEASUREMENT TEACHING, the aiming of ordinary optical transit and centering running program complexity, the error of centralization is big, and be difficult for grasping, affect beginners' enthusiasm and confidence, be unfavorable for the development and the raising of Teaching in University work, can not satisfy the practice of student the surveying instrument basic operating technical ability; Particularly during practising under the dark condition of light, the student need often carry out instrument circle reading and instrument centering, because most of big or middle myopia of student eye person of universities and colleges is more, be easy to make eye fatigue, mood agitation, thereby influence the enthusiasm and the data veracity of student's measure of learning.
Defective in view of the ordinary optical transit, by innovation transformation to the ordinary optical transit, improve its aiming efficient, to spot speed and precision, simplify the operation, reduce the difficulty of engineering survey teaching, improve beginners' enthusiasm and confidence, satisfy the requirement of student, will become the focus and the focus of research and development novel optical transit the practice of surveying instrument basic operating technical ability.
End is got up, the existing following shortcoming of optical theodolite device ubiquity: the one, and pointing velocity is slow, and telescope itself has the effect of amplification target, and the visual field is less relatively, and rough sighting device is too simple.Therefore, seek comparatively difficulty of target by telescope; The 2nd, optics is loaded down with trivial details to a program, the user needs repeatedly to be undertaken to point, instrument leveling, again to point, repeatable operation process such as leveling again by optical plummet, this process has certain randomness, is unfavorable for that the beginner learns and grasps, and has a strong impact on beginner's learning confidence and interest; The 3rd, strictly speaking, optics to point and instrument flatten have to a certain extent low to a precision, speed is slow, has a strong impact on the degree of accuracy and the efficiency of measurement of measurement data; The 4th, the instrument circle reading of ordinary optical transit is thrown light on by the reflection natural light fully, for the environmental baseline bad adaptability, has seriously restricted the use of dark condition such as overcast and rainy, night and tunnel and down-hole etc.
Summary of the invention:
The purpose of this utility model is to overcome the shortcoming that exists in the prior art, by improvement and design to the ordinary optical transit, set up aiming, lighting device, thereby enlarge the service condition and the range of application of instrument, it not only can be waited under the inclement weather environment overcast and rainy, provide a kind of have comfortable, operation and environment for use easily to the user, satisfy the optics longitude and latitude determinator of environment constructions such as medium and small business unit and teaching unit night, tunnel and down-hole.
